First Things First...

Hey

 

So my first carving attempt is going to be with Poenamu.

 

As a totally wet behind the ears newbie to this I will more than likely be highly annoying with a bunch of random questions. Please bare with me!

 

So my poenamu is roughly the shape of a pizza slice approx 4cm thick, 10cm long and 8cm wide.

 

My initial plan was to make some necklaces with it, due to the size it would give me a few opportunities to mess it up. Failing my first question (which is to come) I will have to think more about making one piece from the whole chunk.

 

So... Questions is: What method is best to break the piece up into workable sizes?

 

I know using a saw (with diamond bits??) will be the best recommendation, but as a beginner, I'm not sure if its worth while to buy something that big until I have better skills and know if this is something I would like get serious about!

 

So I will leave this at one question for now. The answer/s will inspire my next question I'm sure!

 

Thanks in advance

You're going to have to get a trim saw in you want to carve stone. You could try a tile cutter with a diamond blade, or get a trim saw from a lapidary supplier. You can get small ones. I'm afraid it is probably a must. You're also going to need some sort of grinding wheel. There is often gear going on TradeMe. Could be worth a look. b

Hi,

Billy is right, you will need diamond tools if you are going carve stone. A tile saw is an inexpensive option to get started, it cuts more roughly and chips out more than a trim saw. Diamond sliters or cut-off wheels for a flex shaft can be purchased cheaply. I used diamond sliters when I was starting out until I was able afford a diamond band saw. Stained glass suppliers etc. can be a good option for diamond tools as well.

I hope that helps.

Not bad price to get you started but here's the thing. Nephrite jade can be very hard, and it takes patience and persistence to become a good stone carver. The problem with these dremel style motors is vibration, heating up and inaccuracy. For the time you need to carve the harder stone the handpiece heats up to a point you can't hold it, and the vibration can make your hand go numb. This has been my experience with Dremels when I first started carving bone. And bone is a lot quicker to carve than stone. New machines may be better.

For a bit more you can get a more specialised carving machine. See the link below. I believe you would have a lot more success with this style of handpiece. I know it's more of an investment, but from experience you won't be far away from becoming addicted to carving, so why not go for it!

I have hunted around for this style of machine, and can confidently say it is well priced. A lot of carvers use Micro Motors or Compressed air driven handpieces, but you're into the thousands then.

 

Hope this helps. b.

Hi Tam, I'm also another Kiwi, (retired and learning). Though I don't use greenstone as it's to expensive, I do use argilite which is slightly

softer by 1 degree in the MHO scale. To rough out my carving I use a 4 inch(115mm) hand grinder with a tile cutter blade. You can get them from the hardware stores (the blades) quite reasonably. Some don't even require water to cut. I never do. I've purchased a small holder for the saw from that

super chief bouteque place--if you know what I'm hinting at!!! A couple of cable ties stop it from from having a slicer action. I've used it for about 3 years and no problems. Just be careful when cutting your stone as you will generally be holding it by hand....Have fun...Colin
